PROCESS FOR SPLICING, PLAITING. AND SEAMING YARNS AND THREADS.

Application filed Sepumber 27, 1923. Seria No. 665,146.

To all whom. it 'may concern:

Be it known that l, FRANK S. VILCOX. a citizen of the United States,l residing at Union, in the county of Union and State 6 of South Carolina, have invented certain new and useful Improvements in Processes for Splicin Plaiting. and Seaming Yarns and Threa s; and I do hereby declare the following to be a full, clear, and exact de- 10 scription of the invention. such as Will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improved process for splicing, plaiting and seeming yarn, thread and the like. 1

An object of the present invention is to provide a process wherein separate strands of yarn or thread may be readily distinguishable during the various knitting and sewing op erations and facilitates the operator in de termining the condition of the work as it proceeds, and to also render-more distinuishable any defects which may occur in t e finished article after it has been completed and removed from a knitting or other machine.

Another object of the invention is to provide a process which embodies the treatment of the thread or yarn with a transitory dye or color so that as a number of strands of the thread or lvarn are introduced into a machine, or the like, and brought into certa'iu definite relations` such relations may be determined as the work preceeds and the ar ticle is. formed.

It is well known to those skilled in the art that splicing and reinforcing of hosiery is done by introducing an extra thread of yarn in the parts to be reinforced. such as in hose:

40 the heel, the toe and sole and also the ankle in half hose While in ladies hose, the s licing is additionally effected at the top o the leg: known as the garter top.

The splicing:r yarns or fibers used are obA tained by the manufacturer in their uatural color which is generally whiter and which are not readily distinguishable from the White color of cotton wool, silk and silk liber used in the body of hoisery. It. is thus evident that when there is a total failure of a machine to function in the splicing opera tion. the operative can notice this condition by failure of the yarn to run from the bobbins but this failure cannot be easily noticed s as there may be a number, half a dozen or so, bobbins with various yarn on them which would normali;Y be out of action at such times so that the ability to distinguish at a glance whether the splicing is being carried on is highly useful. important and necessary.

Duringr the .splicing operation the mechanism frequently does not cease but variousdefects may take place and not be readily noticed, among which may be mentioned the following The splicing may not be introduced at the. proper time, or operate through the proper distance.

The splicing may be skipping.

There are many other irregularities, such as the failure to follou around the stockine` for the right distance. and the like.

It is extremely dilficult and only by very close examination that the above defects may be discovered on account of the lineness of splicing yarns and similarity of color between the same and the body of the hose.

It is a further object of this invention to provide a process wherein these defects may be readily and quickly observed so that correetion thereof may be made. Further.A after the hoisery is knitted the defective goods may be more easily and quickly distinguished from the pe1feet. ones and. may thus be separated. the present invention thus greatly facilitating and making more accurate this inspection and separation of the completed articles.

i yA still further important feature o-f this invention is in the process of plaiting yarn as in the plaitini;r of yarns the fabric is so knitted that, one kind of yarn will be visible on the exterior or outer surface of the fabric while. another qualit or kind of yarn is used on the interior. This is common with the following' knitted con'ibinations:

Silk with cotton backing, fiber silk and cotton` wool and cotton. and many other combinations.

The eliiciency in the plaitim;r opt-ration depends on `the complete covering of the inferior -yarn on strand with the yarn or strand of the better grade. VVheu the yarns are of the same natural color it requires a very close inspection to determine whether' the plaiting device is properly set. present invention therefore aims to provide a process wherein defective setting of the plaiting,r device may become immediately apparent. It is the usual custom to carefully inspect the plaiting devices once or The twice a fla; and to talle a chance that these dei-:ces sill wat as adjusted.

By ilu menen: invention there may he easily am ft-umtacheck all times ot the my wma oi ille planing device.

i'iwt of the invention is to {irl-visiti z i s which may he practiced r Y s u the presen! invention the following is a detailed description i' the present preferred manner of practicing the 'present invention wherein reference is made. to the accompanying drawing which show A side elevation of a knitted article in the form ot a half hose showing splicing thereon which is made arrording to the process ot this invention.

Referring to the drawing which shows a half hose having a body part l() of one color which is usually White, the knitting operi tion is carried on in any 'Well known manner as is also the splicing operation to apply the splicing il' which muy he placed on the article at the desired points. such as at the toe. heel. and ankle as shown in the draw ing and also along the sole or hottom portion of'the hose. This splicin is usually of the same natural color as the ody l0 and hence is not readily distinguishable from the fibers or yarn of the body 10 and defects in the f n e spllcmg operation cannot be readily rieten mined.

According to' the present invention the splicing yarn is first treated with the color or dyeditlerent from the color of the body l() so that. the ortions l0 and 1l will he readily distinguishable one-.from the other and the operation of splicing may he observed and inspected as 1t proceeds to easily and readily catch up defects and thus remedy them or revent further defects of a like nature. he result is that the article produced is as shown in the drawingl with the hodv 'l0 of one color and the splicingr 11 of adiflerent or contrasting' color.

The invent-ion further Qrovides in the process that the color he of atransitory nature so that while for the Purposes of the s licing,r and knitting operation the yarn of t e ditferent parts of the article may be readily distinguishable, the color or dye is transitory so that it may be removed from the yarn or incense tin-cad hy the ordinary laundering process so that the article as a Whole may be sul scqucntly dyed of a uniform color or as otherwise may be desired. The transitory color in the splicing is for the pur oses of contrast hetiycn the yarn or thi-ea during the operation only and after the article is formed it is no longer needed. save for inspct-tion purpose-s. and is not an objection to the later dyeing and treating of the hose.

'This coloring ot the splicing yarn is ad- `vantagemis not only during the operation of nuilting the artic-lc to insure a better formed article. hut is also advantageous in the inspection and separation of erfect from defective articles so as to rea ily separate out seconds and the like which have minor imperfections.

Y This treatment of the yarn or thread with a transitory dye or color may also be used to considerable advantage in plaitin and wherein it is even more important t an in the knitting of hosiery to continuously inspect the plaiting device so as to quickly determine when the same moves out of adjusted position so as to effectively cover the interior with the better yarn or thread.

Any suitable dye or coloring of a transitory nature mav he used as a number of the same are readily'ohtainable on the market, and one which has heen found practically successful azo yellow AW which is made hy thc National Aniline & Chemical Com- ?nny of Charlotte North Carolina, and mown by them as Schultz Number 928.

It is of course understood that this process may he practiced not only with the usc of yarns in plaiting and splicing as above particularly pointed out, but may also be practiced in the use of threads or other strands for sewing or other operations where it is deemed necessary to observe these 0 erations as they proceed for determining t e accuracy and nature of the Work.

What is claimed is:-

That process of splicing, `plaiting and seeming yarns and thread which comprises the treatment of the yarn and thread with a transitory coloring matter different from the colorof the fabric to which the yarn and thread is to he applied and the carrying out of the application of the thread or yarn whereb said application may be observed throng out the entire operation and defects may be readily' noticed.
